hypomyelinating leukodystrophies

Tuesday 15 June 2004

Hypomyelinating leukodystrophies (HMLs) are disorders involving aberrant myelin formation.

The prototype of primary HMLs is the X-linked Pelizaeus-Merzbacher disease (PMD) caused by mutations in PLP1.

Homozygous mutations in GJA12 encoding connexin 47 were found in patients with autosomal-recessive Pelizaeus-Merzbacher-like disease (PMLD).

Exemples

- X-linked Pelizaeus-Merzbacher disease (PLP1 mutations)
- autosomal-recessive Pelizaeus-Merzbacher-like disease (PMLD) (GJA12)
